Catalyst and process for demetallation, desulfurization and dewaxing of residua.

摘要

A catalyst for demetalizing, hydrotreating and hydrodewaxing petroleum residua in a single stage process is described. The catalyst includes conventional hydrogenation/dehydrogenation components on a support of a refractory oxide material and Zeolite Beta. The catalyst has 75% of its pore volume in pores no greater than 100 Angstrom units in diameter and at least 18 to 20% of its pore volume in pores greater than 300 Angstrom units in diameter.
